Remediation Technologies for Cleaning Up Contaminated Sites
EPA has collected information about many types of remediation technologies used to clean up contaminated sites.
The information contained here represents current initiatives related to site cleanup, and includes websites maintained by EPA and other federal agencies and state organizations, as well as recent technical documents.
The information is organized into three sections (combined technology/contaminant resources; technology resources, and contaminant resources) to allow users to locate information by either technology or contaminant of interest.

Superfund Cleanup Technologies
The Superfund Remedy Report (SRR), Seventeenth Edition, was published by EPA in January 2023. The SRR 17th Edition summarizes remedy decisions back to 1982 with a focus on the analysis of Superfund remedial actions selected from fiscal years (FY) 2018, 2019, and 2020. The report includes remedies selected in decision documents (Records of Decision [RODs], ROD amendments, and Explanations of Significant Differences with changes to remedy components) signed in this three-year period. The SRR compiles data on overall remedy selection and remedies for source materials (such as soil and sediments), groundwater, surface water and air related to vapor intrusion. The report appendices summarize all the remedy components selected for sources and groundwater in each individual decision document. View the Superfund Remedy Report (SRR), Seventeenth Edition.

Examples of Groundwater Remediation at NPL Sites (EPA 542-R-18-002). This report highlights a select number of example National Priorities List (NPL) sites where EPA has used innovative and established technologies to restore groundwater for use as a source of drinking water. In these examples, groundwater was successfully restored for drinking water use at 17 NPL sites and significant progress toward groundwater restoration was made at an additional 13 NPL sites where contaminants remain above safe drinking water levels. These sites demonstrate how the Superfund program can overcome challenges related to difficult contaminants of concern and complex hydrogeologic settings (May 2018, 114 pages).

Newsletters on Innovative Treatment Technologies
TechDirect is an information service that highlights new publications and events of interest to site remediation and site assessment professionals. At the beginning of every month, the service, via e-mail, will distribute a message describing the availability of publications and events. For publications, the message will explain how to obtain a hard copy or how to download an electronic version.
The Technology Innovation News Survey contains market/commercialization information; reports on demonstrations, feasibility studies and research; and other news relevant to the hazardous waste community interested in technology development. This report is updated each twice a month.
Federal Business Opportunities (FedBizOpps) contains summaries of procurement and contract award notices issued the previous week that pertain to hazardous waste, solid waste, underground storage tank remediation, and other environmental topics. However, it does not necessarily contain EVERY notice on these topics. Federal Business Opportunities (FedBizOpps) is published weekly.

Clu-In Technology Focus Area
Through the Technology Focus section, CLU-IN provides a compilation of the most relevant information sources on remediation technologies. These resources are presented under 5 categories for each technology such as Technology Description, Applications, Engineering/Regulatory Guidance, Training and References, with a summary and direct link to each one of them. Technologies included range from the established (SVE) to innovative (Phytoremediation). Visit Technology Focus Area
Navy: Remediation Technologies
Informational webpage describes more than 40 in situ and ex situ remediation technologies for soil, groundwater, surface water, and sediment, as well as capping of wastes. Applicability, cost, duration, and limitations are discussed, and links to publications are provided. Visit Navy: Remediation Technologies
Community Guides to Cleanup Technologies
The Community Guide series is a set of 22 fact sheets that summarize cleanup methods used at Superfund and other sites. The series was originally released 10 years ago and was updated in 2012, 2016, and 2021 to include information about new technologies and techniques. Each fact sheet is two pages long and answers six questions about the cleanup method: 1) What is it? 2) How does it work? 3) How long will it take? 4) Is it safe? 5) How might it affect me? and 6) Why use it.

Remedial Technology Fact Sheet - Activated Carbon-Based Technology for In Situ Subsurface Remediation (EPA 542-F-18-001). This fact sheet concerns an emerging remedial technology that applies a combination of activated carbon (AC) and chemical and/or biological amendments for in situ remediation of soil and groundwater contaminated by organic contaminants, primarily petroleum hydrocarbons and chlorinated solvents. The technology typically is designed to carry out two contaminant removal processes: adsorption by AC and destruction by chemical and/or biological amendments. With the development of several commercially available AC-based products, this remedial technology has been applied with increasing frequency at contaminated sites across the country. This fact sheet provides information to practitioners and regulators for a better understanding of the science and current practice of AC-based remedial technologies for in situ applications (April 2018, 9 pages).

In Situ Treatment Performance Monitoring: Issues and Best Practices (EPA 542-F-18-002). The purpose of this issue paper is to describe how in situ treatment technologies may impact sampling and analysis results used to monitor treatment performance and provide best practices to identify and mitigate issues that may affect sampling or analysis. This paper discusses eight potential sampling or analytical issues associated with groundwater monitoring at sites where in situ treatment technologies are applied. These issues are grouped under three topic areas: Issues related to monitoring wells (Section 2); Representativeness of monitoring wells (Section 3); Post-sampling artifacts (Section 4) (April 2018, 15 pages).

Ecosystem Services at Contaminated Site Cleanups (EPA 542-R-17-004)
The U.S. EPA developed this issue paper to provide cleanup site teams with information about ecosystem services. These concepts and tools are useful in communicating the positive results of cleanup in addition to achieving the goals of cleanup. Information about ecosystem services may be considered in characterization of future land use options or design of a cleanup that is consistent with anticipated ecological reuse, depending on the regulatory authority of the cleanup program.
